Laser-aided direct metal deposition (DMD) was used to form a AISI 4340 steel coating on an
AISI 4140 steel substrate. Stress in the coating was relieved before mechanical testing. The …

Manufacturing technologies related to additive processing permit quick and reliable
fabrication of parts, components, thereby enabling savings with respect to economy and …

The as-cast M42 high-speed steels containing different contents of cerium (Ce) were
manufactured to investigate the effects of Ce on the solidification structures at the micro-and …

During laser surface melting of steel components, obtaining the desired distribution of
microstructure and residual stresses with minimum distortion is essential for production …

Three high-speed steels (HSSs) M2, ASP23, ASP30 were surface-melted by a CW 2.5-kW
Nd: YAG laser. The microstructure of the laser surface-melted HSSs was investigated by …

AISI M42 high-speed steel is prone to fracture as a result of its brittle martensitic
microstructure together with abundant carbides located at the grain boundaries. In this study …

In engineering applications, optimizing the properties of die steel has long been a focus of
research. The use of composite materials, which can effectively improve the performance of …

Abstract M3: 2 high-speed steel (HSS) coating was fabricated on one austenitic stainless
steel by laser cladding (LC). The cladded specimen (specimen A) was heat treated at 500° …

Attempts were made to elucidate the effect of nitrogen on primary eutectic carbides in as-
cast and annealed AISI M42 high-speed steel. Particular emphasis was placed on the …

A novel high-vanadium based hard composite coating was synthesized from premixed
powders (V, Cr, Mo, Ti, Nb) on ductile iron (DI) substrate via atmospheric plasma beam …
